Rename SoLID::SolTrackCoords to SoLID::SolTrackInfo
Fix return type of SetPlaneBits::GetBits()

Probably a leftover of copying this template from another...
For MC data, calculate planepattern of MC hits used in track fits
Add fMCHitBits to SoLID::SolTrackInfo and export it as "tr.mchitbits"

This is the planepattern (bitpattern of plane numbers) of true MC hits
that were used in the respective track's 3D fit.
If tr.flags == tr.mchitbits, then all points of the track fit are from
the true MC hit (no fit contamination, no incorrect road matching, etc.)
Ensure synchronization of track indexes for parallel arrays and NewTrackCalc
Use track index passed via NewTrackCalc

This ensures synchronization of the SolSpec::fSolTrackInfo array
which is parallel to the main fTracks array in THaSpectrometer.
Temporarily enable bugchecks even for optimized code

We want better speed, but still trap logic errors in our assertions.
Do not pass ROOTCFLAGS to rootcint, only INCLUDES, similar to latest Podd

ROOTCFLAGS are not needed as parameters to rootcint. In fact, on newer
Mac OS X and possibly elsewhere, some of the extra paremeters cause
rootcint to fail.
